Moniniveliikkeet

Moniniveliikkeet, also known as mass movements, are significant events where large masses of rock, soil, or other materials move downslope due to gravitational forces. This type of phenomenon is common in various landscapes, including mountains, hills, and cliffs, where the slope's angle and geological structure contribute to the instability.

Moniniveliikkeet can be triggered by external factors such as heavy rainfall, earthquakes, or human activities. When an area is saturated with water, its load-bearing capacity is reduced, and the soil or rock loses its strength, allowing it to move freely. Similarly, an earthquake's seismic waves can shake the ground, loosening rocks and releasing stored potential energy.

During a moniniveliikkeet event, the material in motion can range from small rocks to massive boulders and even entire mountainsides. The movement can be slow, taking days or weeks to complete, or rapid, occurring in a matter of minutes. Either way, moniniveliikkeet pose significant risks to nearby communities, infrastructure, and the environment.

Some of the effects of moniniveliikkeet include the creation of scars, scars and new valleys, and landslides. These events can also significantly alter the local ecosystem, causing changes in water courses and potentially disrupting or destroying related habitats.

It is crucial to assess and monitor areas prone to moniniveliikkeet, typically using remote sensing technologies such as satellite and airborne surveys, and through geotechnical analysis. Regular maintenance and management practices can help mitigate these events and their impacts, saving lives and preventing property damage.
